Steemit is made for something like this :)
If a blockchain is perfect for storing data, what would be better than use it to store peoples best ideas? And more generally I think the road to success for Steemit must happen as a creative community where interesting projects are happening, and then written about or vlogged about ( a mutually beneficial feedback loop between projects and online media ).
Another thing : A real idea factory is something the world really needs and no one has so far managed to create it. Which means this is a great opportunity for Steemit.
One aspect I would add which may enhance the value of this concept moving into the future : Collaborative idea development which is then later carried into projects. What I mean is to use the platform to turn a great idea into a fantastic idea including a fantastic plan for execution. Could Steemit work as a think tank where mutual learning goes together with ever more intelligent development of concepts?
One key to make it work might be to give priority to the kind of ideas and concepts which would benefit the entire Steemit community without any downside for anyone. This would remove noise while amplifying the brainpower and energy of the community work.
Incredible potential here :)
